Picking this up after the big summer holidays slump; It turns out that on the Kontron board configuring the watchdog as an "acpi watchdog" makes it work correctly (as a wdat dog rather then itco) For the Dell machines, it seems it's an option that has to configured when ordering the box (!?!). We're trying to find out if there is some way to get it enabled afterwards (it's not a bios setting) or if the only option is to get replacement machines. In both cases it's a rather annoying error condition though as everything seems to work as expected.. It just turns out the iTCO dogs don't actually have any teeth :/ So clearly not something to be fixed in efibootguard (As i don't think it can check for the watchdogs being functional rather then just existing). Just fun with vendors.. -- Sjoerd Simons Collabora -- You received this message because you are subscribed to the Google Groups "EFI Boot Guard" group.
